Paper Making Machine Case – INVT Goodrive800 Series Inverter

INVT 4-quadrant multi-drive inverter Goodrive800 series

With the current global development trend, paper making industry began to pay more attention to energy conservation and environmental protection issues. In the paper making industry fields, the process technology requirement is very high. For example, the product line needs to keep working 7*24 hours, and never stop running except maintenance. To meet this requirement, we should make sure the driving system is able to work stable and continuously. This article will introduce INVT 4-quadrant multi-drive inverter Goodrive800 series which is used in paper making machine.

In some paper making factories, the product line still adopts DC motors. The feedback from end-uses shows us following DC motor disadvantages:

(1) Difficult maintenance

(2) Poor reliability

(3) With carbon brush

(4) High production costs

Advantages of AC motor:

(1) Simple structure

(2) Low cost

(3) High stability

(4) Speed control of high precision

In the current paper industry, the new product line adopts AC inductor motor. With development of AC drivers, the working efficiency and performance get better and better.
